Suppose you have a reaction: 2 A (g) + B₂ (g) A₂B₂ (g) with K. = 1.44 x 10-12, and you start the reaction with [A] = 0.50 M, [B₂] = 1.00 M and [A₂B₂] = 1.00 M. Which statement is correct? a) The partial pressure of A₂B₂ will be almost zero at equilibrium. b) In the ICE table, if x = the change in concentration for B₂ then we can use the approximation that [B₂]. = [B₂].q. c) It will be necessary to use the quadratic equation to find equilibrium concentrations A, B₂ and A₂B₂.
